本研究的目的是检查急性抗阻运动对抑制、工作记忆和认知灵活性等核心执行功能的可能剂量反应和时间过程效应。28名参与者（14名女性; M-年龄= 20.5 +/- 2.1岁）完成了控制条件，并以其个人10次重复最大值的40%、70%和100%进行阻力运动。在运动后15分钟和180分钟进行执行功能测试，以评估运动对执行功能的即时和延迟影响。在运动后15分钟，高强度的运动导致较少的干扰和改善的反应时间（RT）的Stroop任务，而在180分钟的低强度和中等强度的运动导致改善的性能，加减和西蒙任务，分别。这些研究结果表明，急性抗阻运动对健康年轻人的执行功能的影响是有限的和特定于任务的。
The purpose of this study was to examine possible dose response and time course effects of an acute bout of resistance exercise On the core executive functions of inhibition, working memory, and cognitive flexibility. Twenty-eight participants (14 female; M-age = 20.5 +/- 2.1 years) completed a control condition and resistance exercise bouts performed at 40%, 70%, and 100% of their individual 10-repetition maximum. An executive function test battery was administered at 15 min and 180 min postexercise to assess immediate and delayed effects of exercise on executive functioning. At 15 min postexercise, high-intensity exercise resulted in less interference and improved reaction time (RT) for the Stroop task, while at 180 min low-and moderate-intensity exercise resulted in improved performance on plus minus and Simon tasks, respectively. These findings suggest a limited and task-specific influence of acute resistance exercise on executive function in healthy young adults.
